Specification of Letters Patent.

Patented Nov. 30, 1920.

Application filed September 4, 1920. Serial No. 408,377.

To all whom it may concern:

Be it known that I, FRITZ F INOKH, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Gun with Railway Gun-Carriage, of which the following is a specification.

This invention relates to guns with railway gun carriages and consists in an arrangement for the taking of the traverse.

The invention will be described with reference to the accompanying drawings in which- Figure l is a side elevation, partly in sec tion, a constructional example of the gun and Fig. 2 is the corresponding plan view.

Figs. 3 and 4 are views corresponding to Figs. 1 and 2 of a second construction.

In addition Fig. 5 is a section on the line 55 of Figs. 1 and 3 looking from the left and Fig. 6 is a section on the line 6-6 of Fig. 3 looking from the left.

The arrangement shown in Figs. 1,2 and 5 will be described first.

The gun has a railway gun carriage, the frame A of which is carried at its front end on an intermediate support C which is carried on two bogies B B and at its rear end on a bogie B The pivot pin a mounted on the intermediate carrier 0 and the pivot pins 0 0 a mounted on the bogies B, B B are constructed in the form of knuckle pins. The knuckle pin a is rigidly connected to the frame A of the gun carriage and rests in a pan (Z of a slide D which is movable at right angles to the longitudinal direction of the carrier C (see Figs. 1 and 5). The slide D which is guided on ribs 0 (see Figs. 1 and 2) on the carrier C is moved by means of a screw spindle E which is mounted to rotate but not move longitudinally on the carrier C and engages in a female screw thread on the slide (see particularly Fig. The ends of the screw spindle E which project laterally over the sides of the carrier 0 each carry a hand wheel 6 On the frame A of the gun carriage there is mounted by means of horizontal trunnions f the cradle F which carries the gun barrel F.

The rough traverse is imparted to the gun barrel in the well known way 6. g. by running the gun along the rails. To obtain the fine traverse the slide D is moved laterally carriage which is at the same time rocked about the axis of rotation (c of the rear bogie B (see Fig. 2). As, when the frame A of the gun carriage is trained around its front end, it moves over the arc of a circle and the slide D makes a straight line movement, the knuckle pin rotates in the pan d of the slide D and the relative distance between the front bogies and the rear bogies is altered. The bogies are thereby movedv along the rails for a slight distance rela-, 79

tively to each other.

In the construction shown in Figs. 3, 4L and 6 the rear end of the frame A of the gun carriage is also movable laterally. For,

this purpose a screw spindle G, which isl] mounted on the frame to rotate but not move longitudinally, and which is provided with hand wheels 9 engages with a nut 71?. This nut and the pivot pin k mounted in a on which the frame A is supported and slides when motion is imparted to it by the rotation of the screw spindle G.

To obtain the traverse the ends of the,

frame A of the gun carriage are moved in opposite directions by suitably rotating the spindles E and G; the pivot pins a 71, also rotating in their bearing pans 03, Z2 B the simultaneous lateral movement of both ends of the frame A a comparatively large training angle is obtained.

Claims. I

1. A railway gun carriage which comprises bogies, a frame and a gun carried by said frame, means for pivotally mounting v said frame at each end thereof on the bogies and means for traversing the frame relatively to the bogies.

2. A railway gun carriage which comprises two sets of bogies, a frame and a gun 10 .carried by said frame, means for pivotally supporting each end of the frame on one set of bogies and means whereby an end of the frame may be traversed, the pivot point of the frame on the other set of bogies there-,

upon acting as a training axis.

3. A device of the class described, comprising a railway gun carriage, a frame supported thereon, a gun carried by said frame and means for laterally and independently 11o pan A b on the bogie B are carried on a plate H, 80

moving both ends of said frame, for train- 111g said gun, substantlally as descrlbed.

4. A device of the class described com prising a railway gun carriage, a frame' mounted thereon, a gun supported by said frame, and means for traversing one end of said frame which comprises a pivot pin, a slide and means for laterally moving said slide, as and for the purpose set forth.

5. A device of the class describedcomprising a railway gun carriage, a frame mounted thereon, a gun carried by said frame, said framebeing capable of laterally connected to said plate, substantially as described.
